MACHI'N E FOR CUTTING. SHIRT-BOSOMS.

SPECIFICATION forming part of Letters Patent No. 271,925, dated February6, 1833,

Application filed November 13, 1882. (No model.) i

To all whom it may concern:

Be it known that I, EMIL SoHo'rT, a citizen of the free city of Hamburg,Germany, residing in the city and county'of Philadelphia, State ofPennsylvania, have invented a new and useful Improvement in Machinesfor. Sloping orQutting Shirt-Bosoms, &c., which improvement isfully setforth in the following specification and accompanying drawings, inwhich- Figure 1 is a side elevation of the machine embodying myinvention. Fig. 2 is a vertical section of the upper portion thereof.Figs. 3 and 4 are views of opposite sides of a vertical section in lineno a, Fig. 2. Fig. 5 is a top or plan view of the sloping or cuttingtool.

Similar letters of reference indicate corresponding parts in the severalfigures.

My invention consists of means, substantially as hereinafter described,whereby, by the action of a treadle, motion, whenever desired, may beimparted from acontinuously-rotating shaft to a shaft which operates thetool-holder.

Referring to the drawings, A represents the bed of the machine, which issupported on a suitable stand, B.

0 represents a horizontally-arranged rotary shaft, whichis mounted onthe bed Aand made hollow or partly hollow, so as to receive at one end asliding shaft, D, which is formed with a neck, a, for the engagement ofa lever, E, whose bearings are on the bed A or stand B, and has itslower end connected with the treadle F of the machine. The end of theshaft 0 opposite to the shaft D carries a crank wheel, G, the wrist-pinb of which engages with a sliding head, H, the latter being fitted inthe tool-holder J, whereby, by the rotation of the shaft D, and,consequently, of the crank G, rising and falling and sliding motions areimparted to the head H, the effect of which is to raise and lower thetool-holder.

To the shaft D, at the end opposite to the neck a, is secured a pin, K,which projects right-angularly therefrom through alongitudinally-extending slot, 0, which is formed in the wall of thbhollow end of the shaft 0.

L represents a power or driving wheel,which is fitted loosely on theshaft 0, and has connected to its hub, on the inner side thereof, a

lug, M, which is so disposed that when the shaft D is moved outwardlythe connected pin K is brought in contact with said log, it beingnoticed that the side of the bed adjacent to the driving-wheel L isrecessed, as at d, to receive the pin K and lug M and permit rotationthereof with the driving-wheel when so required, the side of the recessbeing closed by an annular plate, N, which is fitted on the inner endof'the hub of the wheel L, and bolted to the bed, thus serving to guidethe wheel and prevent dirt from entering said recess.

The cutter or tool P is shown in Figs. 1 and 5, the object whereof is toform the slope at the top or neck portion of a shirt-bosom, a number ofbosoms, when placed on the table Q, and subjected to the action of thecutter or tool, being shaped at one operation, said table beingvertically adjustable. When a bosom or a number of bosoms is or areproperly placed on the table Q, the treadle F is depressed, the actionof the lever E then moving out the shaft D and bringing the pinKin-contact with the lug M, whereby the continuouslyrotating wheel Limparts motion through the pin K and shaft D to the shaft G, the effectwhereof is to depress the tool-holder and cause the tool or cutter tocut the bosom or bosoms on the table. The treadle is let go, and theaction of a spring, E, on the leverE, forcesin the shaft D, whereby thepin Kleaves the lug M, and the shafts D G cease rotation, thedriving-Wheel L, however, continuing its rotary motion on the shaft 0.As the tool or cutter is in its normal or elevated position, the shapedbosoms are removed and another so pply thereof placed on the table,after which the treadle is depressed, and the other operations named arerepeated. When the pin K and lug M are in contact and the shafts G D arerotated, said pin and lug move in a recess, 01, rflich, formed in thebed A, is a continuation of the recess cl, and when they leave saidrecess d and again reach the recess 01, the pin K is forced from the lugM toward the back ofthe recess d, and, abutting against the wall orshoulder of said recess d, causes the stoppage of the operation of thetool-holder when the same is at its highest position, without, however,affecting the motion of the driving-wheel.

It is evident that the motion of the shaft D may be accomplished by ahand-lever in lieu of the trcadle.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A cutter or tool holder, in combination with a driving-wheel adaptedfor continuous rotation, fitted loosely on a shaft, with which it may becoupled or connected by means of a pin, which engages with both saiddrivingwheel and shaft when said pin is moved, sub stantially asand forthe purpose set forth.

.2. A driving-wheel and a shaft on which it is loosely fitted,'incombination with a sliding shaft, a pin and lug, and a cutter or toolholder substantially as and for the purpose set forth.

3. The driving-wheel having a lug, in combination with the bed havingrecesses 01 d, the shaft 0, the sliding and rotary shaft D, 20 and thepin K, substantially as and for the purpose set forth.

4. The driving-wheel, the shaftsG D, the pin K, and lug M, incombination with the bed having recesses d d and the annular plate N, 25 substantially as and for the purpose set forth.
